Stains burned onto casserole pans

Fill the pan with warm water, add a fresh dryer sheet to the bottom of the pan, and let soak for 15 minutes. Wash and rinse thoroughly. Alternatively, fill the pan with hot water, add a handful of baking soda, and soak for the same amount of time. Scrub with the abrasive side of a scrubber sponge, rinse, and then wash.
